Detailed Pin Configuration

The TLV810ZDBZR is a 3-pin device with the following pin configuration:

1. GND: Ground connection
2. VCC: Supply voltage input
3. RESET: Reset output

Functional Features

• Precision monitoring with selectable threshold voltage options
• Reset timeout period can be fixed or adjustable
• Low quiescent current for power-sensitive applications
• Open-drain reset output for flexibility in interfacing with other devices

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows compatibility with various systems
• Precision monitoring ensures reliable operation
• Low power consumption extends battery life in portable devices
• Flexible reset timeout options cater to different application requirements
• Small package size enables space-constrained designs

Disadvantages

• Lack of adjustable hysteresis may limit its suitability for certain applications
• Limited number of threshold voltage options available

Working Principles

The TLV810ZDBZR operates by continuously monitoring the supply voltage. When the voltage falls below the selected threshold, the device asserts the reset output, indicating a power failure or an out-of-range condition. The reset remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The TLV810ZDBZR is widely used in various applications where reliable voltage supervision is critical. Some of the common application fields include:

1. Battery-powered devices: Ensures proper shutdown and prevents data loss during low battery conditions.
2. Microcontrollers and DSPs: Provides a controlled reset during power-up and brownout conditions to ensure stable operation.
3. Industrial control systems: Monitors power supply integrity to prevent damage to sensitive equipment.
4. Automotive electronics: Protects electronic components from voltage fluctuations and transients.
5. Home automation: Enables safe and reliable operation of smart home devices.
